NORFOLK, Va. (WAVY) – The Navy held a memorial service Monday morning for a Sailor killed in a shooting on USS Mahan at Naval Station Norfolk.

The service began at 10 a.m. at Naval Station Norfolk for Master-at-Arms 2nd Class Mark Mayo. Due to limited seating, the general public was not invited, but the Navy provided a live stream of the service. Taps sounded during the service and Sailors spoke about Mayo.

“Mark Mayo was a hero, not just on that night, but in his entire life,” said MA2 Namon Houston, fighting back tears. “Heroes are not made. They are born. I am proud to say he was my friend.”

Mayo was killed when a civilian truck driver, Jeffrey Savage, tried to get on the ship two weeks ago. When Savage was confronted by a petty officer, he gained control of her weapon and fired, hitting Mayo.

“This type of courage cannot be taught. It is something that resides deep within and is displayed without conscious thought,” said CAPT Robert Clark, Commanding Officer, Naval Station Norfolk. “It is the decision to render aid when many others may watch from the sideline.”
